Yeah dig returned the records for yahoo using the DNS I had in there originally..

I can do DNS lookups using any server i want including the ones I'd entered, that
supposedly caused the problems. So i don't think this would be the case.

No it's not reversed. nslookup is returning Non-Existent host/domain (is there an
option for arpa? I didn't see one in man nslookup)
But it's doing fine with forward resolve and sendmail now. logins aren't delayed.
Thanks,
